To @ZZ whom t may concern:

Be it known that I, WALTER A, GUNN, a citizen of the United States, residing at Lisbon, in the county of Columbiana and' State of Ohio, have invented a new and useful Coupling, of which the following is a specification. c

This invention relates to couplings of that type generally known as basket couplings f and especially adapted for connecting the chains and hooks of chain hoists.

One of the objects of the invention is to provide a coupling so shaped as to embrace and project into one link of a chain and to house and provide a bearing for the shank of the hook, the coupling being very strong in construction, constituting an etlicient connection between the parts, and permitting, if desired, the use ot an anti-friction bearing for the hook. v

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment-ot the invention shown can be made without departing from the spirit of the invention,

ln the accompanying drawings the preferred forms ot' the invention have been shown.

In said drawings,

Figure 1 is a side elevation ot the coupling in position.

Figure 2 is a section on line 2 2, Figure 1, the hook and a ing in elevation.

Figure 3 is a section on line 3 3, Figure l.

Figure l is a view similar to Figure 2 but showing a slightly modied structure.

Figure 5 is a section through a portion of a modified structure.

Referring to the figures by characters ot reference 1 designates opposed members of the basket coupling, these members being duplicates and adapted to be held together at the top by a transverse bolt- 2 and near the bottom by a pair of transverse bolts 3. The lower portions 'of the members cooperate to provide an opening 4 while the upper 'as the opposed members portion of the chain beportionsI of the members are formed .withv` rotation within the yopening 4 and that end y of the shank housed within the coupling has a sleeve or enlargement 8 adapted to bear downwardly on interior shoulders 9 located at the inner end of the f opening 4. The end link 10 of the chain of a hoist is seated within the registering grooves 5- and 1 cometogether between these grooves, as well as at points beyond the outer side ofthe grooves, an

eicient connection between the vlink and i the coupling will be provided and the weight of the load will be transmitted through those portions of the members `within the link 10, thus relieving the bolt 2 from obi jectionable transverse strains.

It will be obvious that by# providing a coupling such as described the chain and hook lcan be connected together securely and the hook will be able to rotate freely relative to the coupling. It desired an antifriction bearing indicated generally at 11 can be arranged within the coupling so as to support the sleeve or enlargement 12 on the hook shank 13. (See Figure 4.)

Importance is attached to the fact that the opposed members of thecoupling 1'it'to gether snugly and when thus secured properly engage the shank and thelink. It is alsofimportant to provide a coupling which houses the shank and fully protects it. The construction described relieves all of the bolts. wherever located, from excessive strains due to the weight of the load..

has been shown in Figure 5 and it will be` noted that the link 10 thus bears against bolt 2 and said bolt supports the entire load.

What is claimed is In a basket coupling for chain hoists and the like, opposed similar members having registering openings in one end for the re'- ception of a hooked shank andregistering as long as they openings in the other end 'for recevng a as `my own, I have hereto aHXed my signachan link, means for holding the members ture in the presence of two Witnesses. tooethewr rml and mea-DS for commenting l n thi-1,) members 2,0 the chain link compljsng TALTER GUNN 5 a bolt exendng through the members and wftnesses:
